Prompts and Error Reporting
4.1
Reviewing The Command Prompts
There are four different types of command prompts.
l Menu Selection Prompt: Use this prompt to make a menu selection. The system requires a numeric
input and displays the valid range of numbers in the prompt that corresponds to the number of menu
items displayed.
l Edit Line Prompt: Use this prompt on database editing screens to get to the desired line number to
be edited. The system requires a numeric input and displays the valid range of numbers in the
prompt that corresponds to the number of menu items displayed. A RETURN (ENTER) at this
prompt will automatically select the first item.
0 Station, Line or Class Of Service Prompt: Use this prompt to get to the particular item or items
that are to be edited. This prompt is waiting for numbers, a range of numbers, or names. You may
specify a single item or multiple items separated by commas, Select a range of items by entering
two numbers separated by a dash. The prompt shows the valid range of numbers but the system will
accept names. The system accepts an item as a name if the fast character is not a number. The
system displays the database information of each item one at a time for viewing or editing. When
you use the ESCAPE key to exit the database information screen, the system displays the next item
in the list. When you use CONTROL C to exit the screen, all list processing stops and the prompt
display returns. When you use CONTROL T to exit the screen, the system stops all list processing
and displays the top level menu.
l Multiple Choice Question Prompt: This type of prompt asks a specific question concerning the
current screen or function and shows the valid responses. Enter these responses as a single character
followed by a RETURN (ENTER).
4.2
Reporting Errors
Pressing unexpected keys (such as letters when only numbers are allowed) or entering an out-of-range
value at a prompt causes the keyboard alarm to sound. The system responds to other types of input
errors by displaying an error message on the screen as soon as it detects the error. If the system detects
a value-out-of-range error, and if the valid range is not currently shown in the display, the error message
includes the valid range of values for reference.
There is one circumstance for which the system does not report an entry error and this is when you are
listing items at a station, line or COS prompt.
In this case, the system processes valid items in the list up
to the first invalid item that it encounters. It does not report the encountered invalid item as an error.
